Azure Functions CLI - such a pretty logo for such an awesome functionality

Azure Function build fails with “Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: Microsoft.AspNetCore.Mvc.Core”

Another fun one with Azure Functions! At least it’s a simple one: this time, I ran into a weird issue while doing some code reusing – well, copy-pasting – between a couple of different projects. I was lovingly hand-crafting some Azure Functions, while suddenly the Azure Functions host would throw me this in ugly, red letters: Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: ‘Microsoft.AspNetCore.Mvc.Core, Version=3.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60’ at Mono.Cecil.BaseAssemblyResolver.Resolve(AssemblyNameReference name, ReaderParameters parameters) at Mono.Cecil.BaseAssemblyResolver.Resolve(AssemblyNameReference name) at Mono.Cecil.DefaultAssemblyResolver.Resolve(AssemblyNameReference name) at Mono.Cecil.MetadataResolver.Resolve(TypeReference type) at Mono.Cecil.ModuleDefinition.Resolve(TypeReference type) at Mono.Cecil.TypeReference.Resolve() at…Continue reading Azure Function build fails with “Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: Microsoft.AspNetCore.Mvc.Core”

How to nuke your Git(Hub) commit history?

Ah – this was a fun one. I needed to figure out how to purge, flush and clear your commit history on GitHub. Turns out it isn’t as easy as clicking a button in the web user interface – the world is apparently not ready yet! 😁 Luckily, it wasn’t that complicated either – and the steps should work for other flavors of git as well. Background Always remember to .gitignore your secrets, folks! And if you forget, pray you’re not committing to a public…Continue reading How to nuke your Git(Hub) commit history?

ILogger binding suddely failing for Azure Functions – what to do?

This article explains another fun issue you might run into, when developing Azure Functions in your local environment.

But if you find it useful, good for you! 😉 Problem So what is it, that’s…Continue reading ILogger binding suddely failing for Azure Functions – what to do?

How to fix a build configuration that’s not available as a build directive in Visual Studio?

This article describes how to fix and tweak your pre-build directives in Visual Studio – just in case they refuse to work properly. Because yeah, apparently that sometimes just randomly happens. But fear not – there’s a stupid and ugly, but definitely thoughtful workaround available! Also, sorry for the confusing title. I’m taking suggestions for a more descriptive one – but this one was kind of difficult to word clearly. Anyway – on to the topic of the day!

Azure Functions runtime throws an "Insufficient memory to continue the execution of the program." error. What do?

How to resolve error “Insufficient memory to continue the execution of the program.” when debugging Azure Functions locally?

This article describes a solution to an error “Insufficient memory to continue the execution of the program.” I was debugging an Azure Function locally and ran into it – it stopped my Azure Function from starting at all. So, this is what I got: Insufficient memory to continue the execution of the program. Ohh… kay..? My development machines have plenty of RAM, surely enough to run an Azure Function! Hell, I’m sure I have enough memory to have Google Chrome running while debugging a pesky…Continue reading How to resolve error “Insufficient memory to continue the execution of the program.” when debugging Azure Functions locally?

How to update SharePoint Framework for an SPFx webpart?

Instead of being stuck on whatever version your SPFx project was originally created with, it’s possible and sometimes required to upgrade it afterwards to gain access to newer functionalities like integration with Microsoft Teams. This process, to me, is comparable to updating the .NET Framework version in your classic web application projects – while it’s sometimes a matter of simple configuration change and a rebuild, most of the time there’s a bunch of steps included and not all of them might be obvious or anywhere…Continue reading How to update SharePoint Framework for an SPFx webpart?

Solving Azure Web Application’s first load perfomance issues

Is your Azure Web Application suffering from absolutely horrible load times every time someone accesses it for the first time every 15 minutes or so? Mine was. It was pitiful. I was developing a web-based service using EF6 and ASP.NET MVC 5, where all the assets were hosted in the Azure. Even though the app was reasonably lightweight and usually responded very fast, the first time someone accessed it in a while it took 20-60 seconds to load AND sometimes even timed out (especially with…Continue reading Solving Azure Web Application’s first load perfomance issues

PowerShell header

Using PowerShell to set ULS logging level to “extra verbose” to catch all the events in the logs

This blog post describes how set the SharePoint’s ULS level to “Extra Verbose” (VerboseEx) using PowerShell. This is not possible using the browser UI, so some POSH magic is required! Luckily, it’s quite straightforward, but to avoid filling your hard drive(s) with huge log files, you should reset the level when you’re done debugging! Description of the solution By default, ULS logging is somewhat non-detailed. This means that a lot of data that could be used to debug issues is omitted. The UI cannot be…Continue reading Using PowerShell to set ULS logging level to “extra verbose” to catch all the events in the logs
